徴とする電動パワーステアリング装置。 A power steering device comprising a steering torque detection means for detecting the direction and magnitude of a steering torque applied to the steering, a reduction gear and a motor mechanically coupled to the steering system, and a control circuit for controlling the motor. The configuration of the control circuit is such that a relay for changing the rotational direction of the motor is provided on the power supply side of the motor, a power element is provided on the grounding side, and the switching relay is activated after reducing the motor current when the motor rotational direction changes. An electric power steering device characterized by:
